The Dyson Sphere has captivated big thinkers for decades. ... Though we might never see our sun encased in a megastructure, or draw our energy from millions of satellites orbiting around it, ...

Alien power plants may be drawing energy from seven stars in our galaxy. Scientists say we could be seeing long-theorised ‘Dyson spheres’ – super-advanced alien technology that harbours the ...

In theory, detecting a Dyson sphere could be a way to find a technologically advanced alien civilization that did not wish to communicate. However, many challenges exist for both building and ...

The search for alien intelligence by looking for Dyson spheres – vast theorised power plants built to encase and draw energy from a star – is inevitably doomed to fail (30 January, p 44). Any ...

This image shows what a Dyson sphere could look like. Signs of these energy-collecting megastructures may have been detected around seven stars.

After surveying 5 million stars throughout our galaxy, researchers identified seven that may host Dyson spheres: super-advanced alien megastructures.

For these and many other reasons, a Dyson sphere costs energy. So we’re going to see how long it will take to recoup the energy investment of building one and what the optimal design might be to ...

A Dyson sphere’s close proximity to a star means that, if they exist, they will heat up and emit infrared energy that could be observed by humans on Earth. Red dwarf stars are the smallest kind ...

A Dyson swarm is a variant of a Dyson sphere. According to RealClear Science, it “would be composed of living habitats, satellites and solar energy collectors orbiting like a net around a star.

We'd need an astronomical amount of resources to construct a Dyson sphere, a giant theoretical shell that would harvest all of a given star's energy, around the Sun. In fact, as science journalist ...
